I have pm'd you my email addy, as the rotor arm is keyed to the shaft, and the shaft has the 2 lobes on it for the phase, if the rotor arm is aligned correctly then the phase must be correct, the scribed line has to fall dead centre in the "path" projected by the rotor arm, even just 1 notch off will cause issues big time.
You would get a far better response from myself via pm, just click on the name, and it gives the option to send a private message, I don't check my email every day, sometimes only every 4-5 days, so pm a lot better.
